Some dubious premises in research and theory on racial differences. Scientific, social, and ethical issues

The scientific premises for looking for statistical differences between groups designated as races (on somewhat arbitrary grounds) are questionable. The explanation of such differences in strictly biological-evolutionary terms is even more dubious. Studies of temperament, basic personality traits, disorders (such as antisocial personality), and specific genetic markers show that there is much more variation within groups designated as races than between such groups. Investigators and theoreticians interpreting such differences on the basis of limited sampling within the three broad racial groups should be careful to avoid selectivity and misrepresentation of data that serve racist ideology, and should be cautious about presenting their theories to the public through inappropriate media forums.     

Women's studies,self-esteem,and college women's plans for the future

Questionnaires distributed at the beginning and end of the semester assessed the self-esteem and life goals of college women enrolled in five women's studies courses and five other courses in related disciplines. The two groups were compared in terms of the changes in self-esteem and goals from the beginning to the end of the semester. The underclasswomen in the women's studies courses tended to express more traditional expected career goals and lowered self-esteem in the posttest. In contrast, the upperclass-women in the women's studies courses reported increased self-esteem in the posttest. Implications for teaching women's studies courses and previous women's studies research are discussed.     

The Papago Psychology Service: A community mental health program on an American Indian reservation

A community psychology service run by the Papago Indian tribe and staffed largely by Papago Indians who have been trained as mental health workers is described. This service is unique among mental health services for Indians in that the tribe has complete control of the funds for the service and sets its own policies. It was developed for a rather traditional Indian group, and the culture, the traditions, and the wishes of the Papago community were respected. Consultation with medicine men was built into the program from the start, and adaptation of mental health techniques to fit the culture is stressed. Before this clinic was established, few mental health resources were directly available to the reservation. Similar to other Indian tribes, the Papagos are economically disadvantaged, with an unemployment rate of over 50%, low educational attainment, and very high rates of alcoholism, suicide, and vehicular accidents. The topics covered are the tribe's view of health programs for its people, the present Papago community and traditional means of treatment, traditional psychotherapy adapted to Papago culture, the indigenous Papago mental health worker, and the non-Indian professional consultant.     

Steady state responding based upon simple and compound stimuli

Two pigeons were trained to perform discrimination tasks along two dimensions, wavelength of a circular spot of light and orientation of a white line. Discriminability among stimuli along these dimensions was established for both subjects by means of a steady state testing procedure. The two dimensions were then combined by superimposing the white line upon the colored background. Subjects were given a series of tests in which a correct response could be made on the basis of either of the two components of the stimulus compounds. Discriminability among these redundant compound stimuli was found to be better than that among wavelength and tilt stimuli alone. A second series of tests was administered using both redundant and conflicting compound stimuli. The results of this test series are consistent with a response strategy in which subjects first examine both elements of a compound and then emit a choice response on the basis of the element that best predicts reinforcement.     

Cultural sex-role expectations and children's sex-role concepts

Middle-class children between the ages of 4 and 8 were interviewed about their sex-role attitudes, in order to determine the extent to which recently changing cultural mores have influenced children's sex-role concepts. The children were asked about their career goals; the careers they would choose if they were the opposite sex; the reasons why they like being a boy or girl; and their opinions regarding the appropriateness of men and women participating in 14 sex-stereotypic occupations and activities. The children's parents provided demographic information. The children expressed very nonstereotypic attitudes towards the 14 occupations and activities, compared to children in recent studies; but they chose very traditional careers for their own choices and opposite-sex career choices, and often gave stereotypic reasons for preferring their own sex. Parents' education, mothers' employment status, fathers' nontraditional careers, and the children's gender predict responses to several of the sex-role-related questions. Implications for research are discussed.     

Self-esteem,self-concept,and the life goals and sex-role attitudes of college students1

Questionnaires that assessed self-esteem, self-concept, educational goals, career goals, preferred and expected career commitment, and sex-role attitudes were completed by 884 male and female undergraduates representing two racial groups and two age groups. Men and women did not differ significantly in terms of self-esteem, but the men described themselves as more attractive than did the women in their age group. For the 18–25-year-old white women, an intelligent, unconventional, and/or nonreligious self-concept predicts nontraditional goals and feminist attitudes, and the interaction between self-esteem and socioeconomic status influences educational goals and sex-role attitudes. For the 18–25-year-old white men, a physically strong and intelligent self-concept predicts higher educational goals and traditional career goals, and lower self-described strength and religiousness and greater intelligence predict more feminist attitudes. Physical self-concept is unrelated to goals or attitudes for the female samples. Self-concept is less strongly predictive of goals and attitudes for the black women and the older men and women. Possible reasons for the sample differences and implications for related research are discussed.     

How much help do repeated presentations give to recognition processes?

A recent experiment by Haber and Hershenson (1965) had shown that in a recognition task one long look at a stimulus was always superior to two or more shorter looks summing to the same total presentation time. In order to explore this more fully and to account for opposite results in a different type of recognition task, as well as in a serial learning task, an improved replication of the earlier study was carried out using very short durations and single letters as stimuli. The same non-reciprocity was found, again strongly favoring duration over repetition as a determinant of clarity of a percept, even though repetition alone was also shown to be a significant independent variable. As a subsidiary finding, an error analysis showed that when a letter was misnamed it was nearly always confused with one that looked like it rather than one that sounded like it. Some discussion was offered as to the role of an auditory information storage in low memory load tasks such as this one, as well as some general implications for information processing analyses of the non-reciprocity of duration and repetition.
